troubles

can
be

repaired
by
simple

adjustment
do

not
disassemble
im

media

tely

Firstly
inspect
and

adjust
the

It

is
advisable

to

CHECKING

OIL
LEVEL

In

checkIng
the
automatic
transmis

sion
the
oil
level
and
the
condition
of

oil
around
the
oil
level

gauge
should
be

examined

every
S
ooo
Ion
3
000

miles
This
is

an

easy
and
effective

trouble

shooting
procedure
since
some

changes
in

oil
condition
are
often

linked
with

developed
troubles
For
instance

Lack
of
oil
causes
defective

opera

tion

by

making
the
clutches
and

brakes

slip
resulting
in

severe
wear

This
is

because
the
oil

pump
sucks

air

causing
oil

foaming
thus

rapidly

deteriorating
the
oil

quality
and

pro

ducing
sludge
and
varnish

Excessive
oil
is
also
bad
because
of

oil

foaming
caused

by
the

gears
stirring

up
the
oil

During

high
speed
driving

excessive
oil
in

the
transmission

often

hlows
out
from
the

brealher

Then

shift

place
it

in

P

position
In
his

inspec

tion

the
car
must
be

placc
d
on
a
level

surface

The
amount
of
the
oil
varies
with

the

temperature
As
a
rule
the
oil
level

must
be

measured
after
its

tempera

ture
becomes

sufficiently

high

Fill

When

topping

up
and

changing

oil
care
should
be
taken
to

prevent

mixing
the
oil

with

and
water

In

pectlns
oU

The
condition
of
oil

sticking
to
the

level

gauge
indicates
whether
to
OVOl

haul
and

repair
the
transmission
or

luok
for
Ihe
defective

part

If
the
oil
has
deteriorated
to
